This invention relates to and has for an object the provision of asimple and efficient hose nozzle embodying a rotary valve disposed'nearthe discharge end of rthenozzle on an axis at right anglesto that of thenozzle andhaving characteristics which combine with certain features onthe body of the nozzle to substantially improve lthe flow, Vrangeanddistribution of water over anarea'beyond the possibilities of otherconventional types'of nozzles. l n To suchend, and more particularly, myimprovements comprehend the provision of a body attachableconventionallynat its rear end to a hose, an axial passage leadingtherefrom to the discharge head at the front. a conoidal outlet adaptedto communicate with said passage indirectly through an olf-set chamberand thence through the valve for regulating the velocity,

through and the jet or spray may be varied at will by but slightadjustment of the valve to obtain a maximum of effective distance,spread and distribution of water over a desired area.

A`further object `is to provide a readily accessible unitwithout usuallyattendant parts and complications and including a. valve with a range ofadjustmentfof less than one'comp'lete revolution'to selectively provideall possible characteristicsto the emitted water to meet Vvaryingconditions of` use.

Other Objects may appear as the description of my invention progresses.

`I have-shown a preferred form of device embodying my improvements inthe accompanying drawing in which: Y

Body I has a taperedpassage l5 leading from socket 2 to a cylindrical valve chamber 6 withinhead 3 and outlet 4 has an outwardly'ilaring outlet passage 4c with itssmaller inner end in communication with a cylindrical valve 6a throughone or more spacedcor pairs of straight slots 1, 1, or a centralpassage8. c

QIt `will ybe noted thatvalve 6a and head 3 are disposedon `an axis atright angles to thatof 7 Claims. (Cl. 299-138) 5-5 of Fig. 3.'

body I and that the upper portion of valve chamber Bis closed-by a wall6' between which and the end 9 of valve 6a, a gasket I0 is held on valvestem II.

\ Afluted operating wheel I2 is fixed to stem II by means of a screw I3for the purpose of rotatably adjusting valve Sa in its seat 6relative-to outlet 4a. A spring I4 is compressed between wheel TI2 andhead 3- and-serves to urgethe valve and gasket upwardly into sealingengagement with wall 8 of `valvercylinder A6.` I n shown in Figs. 2, 3and 5, the head 3`is formed with an offset chamber I5 opposite andcommunicating with the' internal chamber 6b offvalvea and with passage 5of body I which is "closed by a plate I6 secured to head 3 asby screwsvI1. Said Aplate 'is readilyremovable for affording access to head'3 andvalve `lzt'and forv the purposeV of inserting and removing the valve.Hence, the Water freely flows from passage 5 'to chamber 6b fordischarge through the peripheral valve orifices, as at' 1, when thevalveis appropriately adjusted relative to outlet 4a. Otherwise, when valve6a, is properly adjusted, Water is directly transmitted from passage 5through passage 8 of valve 6a to outlet 4a.

Gasket I0 prevents leakage of water around valve 5a and around stem II.a

The orifices 1 and 8 of valve 6a are so disposed as to provide outletclosing segments Gc, Gc, etc., between the openings of passage 8 andorilces 1, as shown in Fig. 4, so rthat'when the valve is adjusted withone of said segments opposite outlet 4a, the outlet may be either whollyor partly closed against discharge of water from the nozzle. In some'cases, the extent of a segment 6c may be less than the circumferentialdistance between an orice 1 and an opening of passage 8, in which case apartial merger of an axial jet from pas. sage 8 and jets of fiat crosssection from orificial slots 1 are effected and serve to diffuse anddis- `chamber 6b throughvv orices 1 and also downwardly fromend I Iofthe valve so that it emerges from orices 1 at an angleand is againdeflected by the conoidal wall `of`outlet 4, thereby causing breakingup'of a streaxnor jetVV into globules and a spreading of theresultant-spray over a substantially wide area at any-velocityand for asubstantial distance forwardly ofthe nozzle'urn,A

der maximum velocity.

When, for instance, valve 5a is adjusted with la pair of spaced oricialslots, as shownV in Figs.

, or,` collide at a point forwardly of the'nozzle and causeaI breakingup vofthe water intoglobules Y from such point of intersection and aconsequent dropping and possible lateral spreading of Water from suchpoint-throughout the remaining effective path of the merged stream.

It may be noted also that passage 8 of valve 6a has a major area at oneextremity and a minor area at its other extremity which permits of thecreation of minimum and maximum .velocities of Water at outlet 4a. whenthe valve is adjusted with the portion 8a of minimum area rearmost orthe portion of maximum area rearmost, respectively.

The essence of this invention is in the provisionof body l arrangedtoincrease-the velocity of-flowtoward its outlet,'the provision of thecylindrical valveseat and valve therein rotatable on axis at rightangles to the axis of the body andV formed with iperipheraloutletscapable of selective registration with the outlet of the body, means fordirectly Vand indirectly rconducting Water to and through the valve toproduce jets, streams orsprays ofvaried character, means atthe-outlet'for spreading. the ejected water, and means for readilyinserting and removing the valve, all considered independently, ortogether.
